In October 1996, when the manufacturer of blood collection needle made a serological survey on site, it tried to use a disposable blood collection needle instead of a triangular needle to collect blood from the earlobe. It was found that it has the following advantages.
1、 Save time
Disposable blood collection needle is a finished product after detoxification. It does not need to be disinfected when used, so it can save time and improve work efficiency: more than 500 people were collected within 2 hours by 6 people, including the author, and more than 40 people per hour. The work efficiency is nearly one third higher than that of the original three edged needle.
2、 Convenient
The special design of the tip of the needle limits the depth of the needle into the skin. So that the examiner, especially the novice blood collector, can easily master it.
3、 Safe
When a disposable blood collection needle is used for blood collection, each person has one, which is discarded after use, so as to eliminate the cross infection of blood borne infectious diseases.
4、 The subject is easy to accept
The double-edged wound caused by the puncture of disposable blood collection needle into the skin is one third smaller than the three edged wound caused by the use of three edged needle, which reduces the pain of examination and is easy to be accepted by the subjects, especially the young group. In addition, the price of disposable blood collection needles is low (the market price is only 0.03 yuan per needle), and the subjects can afford it. Therefore, the disposable blood collection needle is very suitable for large-scale serum census on site.
